My chicken coop caught fire two nights ago, luckily we caught it before the fire spread to the nearby woods, but not before it could claim the life of one of my roosters, the other 12 are mostly alright, but suffering severe smoke inhalation, What can I do to help them breathe? one hen in particular is having the most trouble, gasping and moaning for each breath, is there any way I can help her breathe better?
